There is only one version of this question that you have access to.

Question statement

Sea el cuadrado de la figura sometida a un estado de deformación plana ( $\varepsilon_{13}=\varepsilon_{23}=\varepsilon_{33}=0$ ) homogénea.

De esta deformación se sabe lo siguiente:

La deformación volumétrica vale $\varepsilon_v=\var{epsion_v}$
La variación angular del ángulo ADC vale $\var{delt_12}$ radianes.
El alargamiento unitario del lado EC vale $\varepsilon_{EC}=\var{eps_chi3}$

Responde a las siguientes preguntas (usa maple para resolver el sistema de ecuaciones):

Give any introductory information the student needs.

			Name	Type	Generated Value

a_11	integer	5
a_12	integer	1
a_22	integer	-5
epsion_v	rational	0
eps_chi3	decimal	dec("0.003366025403784438")
delt_12	rational	1/500
delt_45	number	-0.01
